【问题描述】：
我尝试使用 Java 和 Jetty 实现一个简单的聊天应用程序。我已按照博文下面给出的所有步骤进行操作。
当我尝试运行 mvn jetty:run 时出现以下错误：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile (default-compile) on project sample_application: Compilation failure
[ERROR] /home/rajee/Documents/techZHomeSample/src/main/java/ToUpper356Socket.java:[12,1] error: annotations are not supported in -source 1.3
[ERROR] -> [Help 1]
[ERROR]
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

我在下面共享了我使用过的 Java 和 Maven 版本：
Apache Maven 3.0.5
Maven 主页：/usr/share/maven
Java 版本：1.7.0_03，供应商：甲骨文公司
Java 主页：/usr/local/jdk1.7.0_03/jre
默认语言环境：en_US，平台编码：UTF-8
操作系统名称：“linux”，版本：“3.13.0-76-generic”，arch：“amd64”， 家庭：“unix”
您可以在下面找到 pom.xml。

谁能帮我找出问题所在？
P.S - 我正在使用 IntelliJ Idea 14.1.3
